Delaware Voter Survey 2016: Methodology and topline results

Abstract

The National Agenda Opinion Project research was funded by the University of Delaware’s Center for Political Communication (CPC) and the William P. Frank Foundation. The study was supervised by the CPC’s Research Director, Paul Brewer, a professor in the Departments of Communication and Political Science & International Relations. Results are based on telephone interviews with a representative sample of 900 registered voters. Telephone interviews were conducted by landline (450) and cell phone (450, including 187 without a landline). The survey was conducted from September 16-28, 2016, by Princeton Survey Research Associates International. Statistical results are weighted to correct known demographic discrepancies. The margin of sampling error for the complete set of weighted data is ± 3.8 percentage points. Readers should be aware that in addition to sampling error, question wording and practical difficulties in conducting surveys can introduce error or bias into the findings of public opinion polls
